2009-04-18hpt366: fix HPT370 DMA timeoutsSergei Shtylyov
The big driver change in 2.4.19-rc1 introduced a regression for many HPT370[A] chips -- DMA stopped to work completely, only causing endless timeouts... The culprit has been identified (at last!): it turned to be the code resetting the DMA state machine before each transfer. Stop doing it now as this counter- measure has clearly caused more harm than good. This should fix the kernel.org bug #7703.

2009-04-18thinkpad-acpi: bump up version to 0.23Henrique de Moraes Holschuh
Plenty of high-profile changes, so it deserves a new version number. Features added since 0.22: * Restrict unsafe LEDs * New race-less brightness control strategy for IBM ThinkPads * Disclose TGID of driver access from userspace (debug) * Warn when deprecated functions are used Other changes: * Better debug messages in some subdrivers * Removed "hotkey disable" support, since it breaks the driver * Dropped "ibm-acpi" alias Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Len Brown <len.brown@intel.com>
2009-04-18thinkpad-acpi: simplify module autoloadingHenrique de Moraes Holschuh
Simplify the module autoloading a great deal, by keying to the HID for the HKEY interface. Only _really_ ancient IBM ThinkPad models like the 240, 240x and 570 lack the HKEY interface, and they're getting their own trimmed-down driver one of these days.

2009-04-18thinkpad-acpi: fix LED blinking through timer triggerHenrique de Moraes Holschuh
The set_blink hook code in the LED subdriver would never manage to get a LED to blink, and instead it would just turn it on. The consequence of this is that the "timer" trigger would not cause the LED to blink if given default parameters. This problem exists since 2.6.26-rc1. To fix it, switch the deferred LED work handling to use the thinkpad-acpi-specific LED status (off/on/blink) directly. This also makes the code easier to read, and to extend later.

2009-04-17Input: ucb1400 - use disable_irq_nosync() in irq handlerBen Nizette
disable_irq() waits for all running handlers to complete before returning. As such, if it's used to disable an interrupt from that interrupt's handler it will deadlock.

2009-04-17sata_mv: workaround for multi_count errata sata24Mark Lord
Workaround for errata SATA#24 in sata_mv. This errata affects WRITE_MULTI* commands when the device multi_count produces a DRQ block size >= 4Kbytes. We work around it here by converting such operations into ordinary PIO_WRITEs instead. Note that this might result in a PIO FUA write unavoidably being converted into a non-FUA write. In practice, any system using FUA is also going to be using DMA rather than PIO, so this shouldn't affect anyone in the real world.
